Visionaries and
Innovators
The early visionaries dreamed of humankind one day going
into space and together with the innovators made it happen. Many of the
visionaries and innovators we recognize today share an undeniable desire to make
the dream a reality for anyone who wants to go.
Peter Diamandis -- Popular favorite garnering
dozens of nominations from readers, Diamandis co-founded the Ansari X Prize, a
$10 million purse that has inspired more than 20 teams to built reusable
spacecraft in hopes of being the first to send three people into suborbital
space and back twice in two weeks and to claim the prize. He also is a
co-founder of International Space University.

Paul Coleman -- The former president of the
Universities States Research Association, Coleman has been a tireless proponent
of making space accessible to university researchers. In the early 1990s,
Coleman served on a White House panel that urged converting surplus ballistic
missiles into satellite launchers. He also has been active in working to get
access to the space shuttle for university experimenters.
Bill Gaubatz and Jess Sponable -- For their work
on the Delta clipper X (DC-X), later known as the Clipper Graham, an
experimental single stage to orbit vehicle that never got the funding it
deserved despite early flight successes. The DC-X was built under contract at
McDonnell Douglas with Gaubatz serving as the project manager responsible for
its design and construction. The reusable rocket repeatedly flew from the White
Sands Missile Range starting in the early 1990s.
Mike Griffin -- From the number of advanced
degrees Griffin has racked up over the years -- five masters and a Ph.D. (not
that we are counting) -- you might conclude that Griffin is your classic ivory
tower type, all theory and no practice. But that would overlook the role Griffin
played in the early days of missile defense, as the NASA executive in charge of
the Space Exploration Initiative, as Orbital Science’s chief technologist, the
president of the CIA venture capital firm In-Q-Tel, and currently as the
director of Johns Hopkins University’s Applied Physics Laboratory. Griffin has
been an outspoken advocate of finding innovative and affordable ways to conduct
human and robotic space missions.
John Mankins -- One of NASA’s classic big picture
guys, there has hardly been an advanced concepts project and human space
exploration strategic plan that hasn’t benefited from Mankins’ input. He is well
known for his contributions to space solar power, and also deserves credit for
creating the MagLifter electromagnetic launch assist system concept and for
inventing technology readiness levels to assess a given technology’s relative
maturity.
Gerard K. O’Neill -- Dozens of readers nominated
O’Neill for this list, a real testament to the impact he had on so many people.
No other person who lived and worked in the last 15 years was mentioned nearly
as often. Although he died in the early Spring of 1992, O’Neill’s book, “The
High Frontier,” continues to inspire new generations of space enthusiasts. His
testimony to the U.S. Congress about such issues as solar power from space and
living in artificial space habitats fueled the grass roots activists and
inspired a new generation of innovators who are working to make space a reality
beyond government programs. O’Neill’s descendents are determined to prove that his
vision of private groups getting things done in space in a way that is truly
faster, better and cheaper than the things the big bureaucracies do. Even within
NASA’s large structure, O’Neill’s followers are self-organizing into work groups
for specific missions that were unthinkable 15 years ago. Unthinkable, that is,
for those who hadn’t spent a few minutes with O’Neill.

Rutan | |
Burt Rutan -- The legendary aircraft designer is
blazing a trail that many hope will open the final frontier to regular visits by
paying commercial customers. Rutan’s Scaled Composites is the odds on favorite
to win the X Prize, a $10 million award that will go to the first privately
financed organization to launch a vehicle on a suborbital trajectory twice in
two weeks.
Sir Martin Sweeting -- Sweeting turned Surrey
Satellite into the world’s microsatellite builder. Under his guidance this
British company has trained a new generation of spacecraft builders throughout
the world helping countries like Turkey, Thailand, Korea and Chile enter the
space age. Surrey also was the architect of a new global disaster monitoring
system of imaging satellites.
Rick Tumlinson -- Part agitator, part operator,
Tumlinson has spent the past two decades advocating human exploration and
settlement of the solar system and has been a strong advocate of creating
commercial opportunities at the Russian Mir space station and at the
international space station.
Bob Zubrin -- Zubrin’s vocation could best be
described as Mars evangelist. No one is as passionate, as aggressive, as
relentless and sometimes just downright annoying as Zubrin. He has made getting
humans to Mars his life’s passion and he has spread that passion like a circuit
preacher. Founded six years ago, the Mars Society is a thriving, vibrant
organization with an active membership.
Angels
Every field has them -- angel investors who often put
their personal convictions ahead of return on investment. In recent years, more
than one space entrepreneur has been given a shot at turning their dreams into
reality thanks to some of these fabled money men.

Paul Allen and
Burt
Rutan | |
Paul Allen -- The Microsoft co-founder made
headlines this year as the financial backer behind SpaceShipOne’s successful
suborbital flight, bringing affordable space travel that much closer to becoming
reality. Allen also has donated millions to the Search for Extra Terrestrial
Intelligence Institute and bankrolled construction of the institute’s Allen
Array Telescope, a dedicated radio astronomy telescope scanning the skies for
signals from beyond. Thanks in no small part to Allen’s largesse, SETI is back
in NASA’s good graces, joining the U.S. space agency’s Astrobiology Institute.
Allen was also the driving force behind Seattle’s Science Fiction Museum, which
opened its doors in 2004.
Walt Anderson -- Anderson is the money man behind
such shoot for the stars ventures as MirCorp, the Foundation for
Non-governmental Development of Space, Rotary Rocket, Constellation Services
International, Satellite Media Services and LunaCorp. Many Anderson-backed space
ventures have yet to leave the launch pad, and some of them probably never will.
“The joke is I make money in telecom so I can [throw] it away in space,”
Anderson said in 2002, announcing the start up of a new satellite servicing
venture dubbed Orbital Recovery Corp. “I’m done being an angel investor for
crackpot space enthusiasts. I want to be the guy who really commercializes
space.”
Steve Kirsch -- The founder and former chairman of
Infoseek funded construction of the Mars Society’s Flashline Mars Arctic
Research Station in Canada’s Devon Island.
Walter Kistler -- The Swiss-born physicist and
inventor combined his vision with his own personal wealth to start Spacehab in
the 1980s and later Kistler Aerospace Corp., a Kirkland, Wash.-based firm that
has spent over a half-billion dollars in pursuit of an affordable reusable
launcher.
Remigius Shatas & Bob Asprey -- This
Huntsville, Ala.-based duo have been a reliable source of start-up capital for
such entrepreneurial efforts as Space America, SkyCorp, Constellation Services
International and Rocketplane Limited.
